Can't Get No Satisfaction?


One of the fun and amazing benefits of homeschooling is the things you learn while you study the material you are teaching your children. 

I checked out a great book from our local library (and I may purchase it for our own) called, "The Way We Work -- Getting to Know the Amazing Human Body," by David Macaulay. This is a reference book with great pictures drawn by the author, which break down very small parts -- like the atom -- into (relatively) understandable pieces.

I was struck by some of the language while reading this section about building atoms:

     "Left to their own devices, most kinds of atoms will contain the same number of electrons and protons . . .it is the attraction between positive (protons) and negative (neutrons) charges that holds an atom together.

     "Electrons travel around the nucleus in specific orbits called shells. Each shell can hold only a certain number of electrons, and as each one reaches capacity, a new one is formed . . .

     "When the outermost shell of an atom is full and there are no more electrons to place, that particular atom is said to be stable. This is not usually the case...Most atoms...spend their lives continually seeking fulfillment."  (page 19, emphasis mine)

Here is one of the most basic components of our body, too small to be seen by the naked eye, and if it had its way, it would make sure it was satisfied. Yet it is always seeking to be fulfilled.

If tiny particles in my body are not satisfied, is it any wonder that I struggle to be fulfilled with my life -- what I have, what I eat, who I am?

We will never be content without the indwelling of the Spirit of God, through the saving power of Jesus Christ in our life. As the psalmist says:

"Whom have I in heaven but You? And besides You, I desire nothing on earth," (Psalm 73:25 NASB).


And speaking of science-y things, the THESIS Science Fair is this year!

I know it is early, but I'm mentioning it because Jessica Peterman, who is teaching the middle school class some fun and exciting Mythbusters-based science, has created a timeline to keep the fair from sneaking up on you!

This is for the middle school class, but it could be used by anyone. Just click here to get a copy you can download.

Science Fun with Gelatin

..and lots of candy!

Who knew science could be so fun, and calorie-filled? (ha)

For science this year, we are using Apologia's Young Explorer Series book "Exploring Creation with Human Anatomy and Physiology."  So far, we are all enjoying it very much.


Do you know the difference between anatomy and physiology?

Sara says, "Anatomy is how your body is made, and physiology is how it works."

We made cell models out of gelatin, which represented the cytoplasm. Then we inserted several different candies to show the different organelles, or "little organs," such as mitochondria (ever read "A Wrinkle in Time?"), lysosomes, and the endoplasmic reticulum, to name a few.











Is it obvious that Kyla does not like gelatin?
